while creating the csr file i wrote my server name has www.myserver.com and not mail.myserver.com. (i read somewhere that comodo will add myserver.com along with the www.myserver.com) i realised what could be a potential error after purchase ... i really hope this will not be a problem.
the bundle file has been created and its contents, the .crt and the .key files from comodo are copied into the imscp domain ssl page. everything went fine.
now i want to configure the postfix server. i tried to follow this link but the paths are different to imscp .... the link is www.improvi.in/blog/?p=54
is there a document guide that i could follow or if one has time can explain all the paths settings and other adjustable areas that i need to do in order to get my mail server secured then finally a way to verify that ssl is working with my mail server.
